SCOPE CARRIED FORWARD
Phase 0: typed records, bridge provenance and append-only non-retroactivity
Phase 1: factorization/fiber obstruction for independently fixed targets
Phase 2: origin-tagged ancestry, first determinacy stage and exact DAG cuts
Phase 3: cyclic least provenance, finite seed-grounded support and fixed-point selection

PHASE 4 INDEPENDENCE CLAIM
Phase 4 studies a different coordinate: whether current nonmembership can be
upgraded to stable absence over a supplied finite extension family, or to a
distinct negative claim-code. CBE-4 uses only finite positive support closure,
the declared extension family and its maximal frontier. MCW-4 localizes every
failure of stable absence in a minimal enabling counterextension. BND-4 makes
the completion boundary an explicit input. No external predecessor is a proof
premise.
